Can't connect to Impala 3 CDH6


I am unable to connect to Impala using the datasource connector. I get the error message “expecting list of size 2 for struct args”.

CDH 6.0.1 with Impala 3.0.0-cdh6.0.1
Redash 5.0.1+b4850 (via docker image)

I think it might be a thrift problem, but the bug reports seem to indicate it was fixed. Any ideas?
